soft deprecation for jsx-space-before-closing

[dnalborczyk]

The introduction of jsx-tag-spacing makes jsx-space-before-closing obsolete.

#1070
#693 (comment)

since the plan is to deprecate jsx-space-before-closing, I think it would be already helpful and less confusing - as it was for me - if this would be already mentioned in the docs.

something like:

Note: This rule will be deprecated in the next major release. Consider using jsx-tag-spacing instead.

Mind if I do a PR?

Sounds great!

You can also mark the rule itself as deprecated in its metadata.

I believe this is a must have. Because if a project has both configuration, with different settings, eslint will keep complaining that there's an error.

Looks like this is already in the docs via https://github.com/yannickcr/eslint-plugin-react/pull/1070/files#diff-682c810c832cf33406eede243921fd42
